Cinnamon Hummingbird is completely cinnamon below, with bronze-green upperparts. It is common in dry forests, where it is present year round; but in seasons when resources are less available, some individuals may move to higher elevations, some even reaching pine and pine-oak forests. Cinnamon Hummingbird occurs along the Pacific slope from western Mexico south to northwestern Costa Rica, and also on the Yucatan Peninsula in southeastern Mexico and in Belize.
